USB not recognized (Device Descriptor Request Failed)

Q:USB not recognized (Device Descriptor Request Failed)

I have a flash drive that I previously used in public computer lab (where many viruses linger) the other day to do my work. As I got home, the flash drive isn't working anymore, saying "USB Device not Recognized". I also noticed that it really took me a while to finally, safely remove it from the computer lab's PC. So I actually wonder if it actually removed my flash drive properly.

On Device Manager, it says "Unknown USB Device (Device Descriptor Request Failed)".On the Properties, the device status says "Windows has stopped this device because it has reported problems. (Code 43) -- A request for the USB device descriptor failed."

Things I have tried:- Shut down my PC, unplugged power and removed battery, waited for a while, booted my PC and try plugging in again.- On Device Manager, uninstalled it and scanned for hardware changes, it still returns as "Unknown USB Device".- On Device Manager, I clicked "Update Driver Software..." and it returns me a message saying "The best driver software for your device is already installed".- Unfortunately, when I visited Kingston's website to check if there is driver for this specific flash drive, there isn't any... "There are no downloads or drivers available for this product".- Used Windows 8's Troubleshooting tool. It only detected my problem, but was unable to fix it.- I also tried plugging it to other devices that are running on Windows XP, Vista and 7, none does any better.

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device.
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

Now when i completed the installation, i connected it and i had this error:Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.I used slimdrivers to update all the other drivers, in case it was a conflict causing the error.I checked via command prompt with command "pnputil -e" and i saw a driver from the vendor of the device listed, so it is installed correctly i think.I tried all USB ports i have, 3.0 and 2.0 on one side of laptop and 2.0 on other side.

When on device manager, if i click update drivers and choose the "let me pick from a list of device drivers.." i don't see the company name of the device.

i saw that another guy posted a really similar problem on SevenForum and he figured out how to force windows to use the drivers but he didn't post the solution.. Here is the post: Can't get Windows 7 x64 to use the drivers I've installed repeatedly Solved - Windows 7 Help Forums

A:USB device not recognized. Device descriptor request faile

I am having the same exact problem as you, Cattanius. I couldn't get it to connect to my computer over 2 years ago and then just decided to try it the other day. I didn't expect anything to show up in device manager because I thought the usb port was fubar, but then I see the same message you got and all of the sudden there's hope! I hope.

Let me start out by saying that I've googled the shit out of this problem, tried several things, and nothing worked.

I have a D-Link USB 2.0 Hub that I got about a week ago. It's been working awesome up until recently. It's a plug and play device, however windows is failing to recognize it, and thus making everything I have plugged into it unusable.

In the 'Device Status' box it says:

Code:
Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.

And in the 'Events' tab, there's a few listed, I'm not sure if they are much help:

hello guys in my device manager there is a yellow triangle on a usb device driver saying : a request for device descriptor request failed first i thought maybe 1 of my us ports not working but when i tested all ports are working even card reader but the error is still there i updated drivers (chipset - etc) but it didnt help so i want to know how to get rid of that error and what is the problem with my laptop?note: sometimes when i trun on my laptop that error is gone mysteriously and most of the times its showing up note: i recently changed my wireless adapter tho the orginial adapter was a bt/wifi combo but the new one is just a wifi adapter and i have an ssd installed instead of dvd optical drive and both are working wellnote: things i already tried: disabling fast boot-updating generic usb drivers-taking out battery for 5 minutes-updating drivers

Few days ago suddenly my Logitech MX master mouse (bluetooth connected) stopped working. Then I figured that Bluetooth can not be enabled. Then I saw that in Device manager have problem with unknown usb device, which device decriptor failed. Usb ports are without any device connected. All four of them empty now. Any kind of windows, usb/bluetooth driver update/uninstallation is not helping, so this is why I am trying to find help. So please help.

hey, im having problems with plugging in my mouse to any USB port, this just started around an hour ago. ive checked on the brand's website which carried no complaints on problems like this with the same mouse. tried pretty much everything, even looking
it up on youtube and forums... Nothing has worked, worser still, i got it for christmas and its stopped working, ive looked though the device manager too. Please try and help me, if u can. I use Razer Naga Waith Red if that helps

thanks,
onyx

A:Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed.

Hi onyx,
This error means a device driver notified the operating system that the device failed. This circumstance can occur if the device hardware fails or if the device driver fails.
Have you tried to update the device driver for test?
Please follow this guide trying t resolve this issue:

I was just working happily when my Microsoft Bluetooth Mouse just suddenly stopped working.The Bluetooth settings page says "Bluetooth is turned off" and there are no options on the settings page or the system tray to turn Bluetooth on.The Device Manager now has "Unknown USB device - device descriptor request failed" where it did not before.Other devices all seem to be working fine - USB devices plugged in are being recognized and work properly. Only BT seems to be broken.I've tried:uninstalling the device and rebootinginstalling the latest updated chipset drivers from the dell websitewindows updatespretty much all of the advice here: http ://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed

So in desperation I just went into BIOS settings to see if there are any BT settings that may have become disabled. I didn't see any, and I didn't change any other settings.After rebooting, BT and my mouse is now working again.Something seems to be really flaky here, but hopefully this will help others with the same issue.

Hello, ok so after recently doing a clean install of windows 10(please don't get me started on that mess). my system has been plagued by random usb drops. it's where everything connected via USB suddenly disconnects then reconnects out of the blue. well I was using a Rosewill Transenclosure RX200R-APU-25B USB 3.0 dual 2.5 hard drive enclosure and transferring files from one drive to another (connected via USB) when one of these drops occurred. Now whenever I plug in my hard drive enclosure in a windows warning pops up and says "the USB drive that was just connected Malfunctioned and could not be installed" and in system manager it says "Unknown USB device (device descriptor request failed)". I know it's not the hard drives because I can remove them and use another connection and they work fine, all files intact. It's just now my hard drive enclosure won't recognize. This also happened to a "Loot crate exclusive Game of Thrones stark sigil 4GB USB stick I plugged in and turned into a windows 10 install drive. When I plugged it into use it after the windows media creator said it was done the USB stick was raw and unformatable. Please help. Microsoft keeps telling me it's a hardware issue even though it happened on two different systems. both operating windows 10 never any issue with windows 7 or 8.1

Massive problem I have encountered since buying a new laptop pre-installed with Windows 8.1

I have 3 external USB storage devices - 1x Corsair "Slider" 64GB, 1x HiTachi Touro 750GB, & 1x HiTachi 4TB external drive. ALL drives are coming up with the same error message and are not being recognized by Windows 8.1

The strange thing is, I also have another 2 PCs - one with Win7 and one with WinXP and the drives work without issue.

I've spent the last 4 days scouring the net looking for answers, and thus I am here hoping someone can shed some light as to why ALL of these drives do not work on this new laptop pre-installed with Windows 8.1?

Even stranger still is I have other thumb drives, a cheap Transcend 32GB (which is USB3.0) and a few cheapo (USB2.0) drives of various sizes by Strontium, Lexar and so on which work perfectly.

But the one that has me o.O is an expensive 64GB thumb drive called the Mach Extreme which also works perfectly with this laptop???

So all up 2x HiTachi drives & 1x Corsair thumb drive are not working and its driving me bonkers!

If no drives worked at all, then I would be seeking the manufacturer for maybe a faulty component. Dodgy USB ports, or maybe a motherboard problem. But having a handfull of drives, of various makes, sizes and both USB3.0 - 2.0 fully working leaves me scratching the old chrome dome as to what could be the issue

I've always updated drivers, WinXP, Win7 and so on, the same way - download the driver, go into device manager and select browse, then point windows to the downloaded driver to update the necessary files. Its always worked that way for me for as long as I can remember.

Not so it appears with windows 8 - for some strang reason.

For me I had to update to the latest Intel Chipset Drivers, but instead of the tried and trusted methos above, you simply hit the setup.exe and let windows 8 do its thing. Believe it or not, but this fixed the issue.

Yes I had already updatd to the latest Intel Chipset Drivers using the device manager method, and yes windows "did" update ...someting??? But the USB devices were still showing the Unknown USB Device error. But using the setup.exe fixed the everything and all my USB devices are now working perfectly with Windows 8.

How, why, who knows, but I hope this works for others with the same problem.

having trouble installing an Epson WF-2530 printer onto win 8.1 machines. i have 3 win 8.1/64 bit machines. it will install and is working on only one. used the same installation disc, and install process, and cables with all 3 machines. googling the problem shows plenty of stuff mainly updating drivers. done that, still no good.Not sure why it works on only one, a generic clevo laptop w550eu.thoughts??? the installation process stumbles when it asks you to connect the printer cable to the computer.

Was trying to plug my Toshiba 1tb External hard drive in to retrieve music off it and it wont recognize the drive. Device manager revealed the yellow triangle and error message. It works on my wifes hp streambook and also my kids stream book both are running wondows 10 like mine. I have tried nearly 10 different suggestions from google searches and have gotten nowhere. The only thing I couldnt try was turning off the usb in the power options, for some reason mine doesnt display that option. My notebook only has 1 usb port so I cant try a different port. Any suggestions or fixes?

My computer keeps telling me Unknown USB Device (Device Descriptor Request Failed), so I looked up how to fix it and they told me to uninstall it then scan for hardware changes and it will reappear working properly. Only it did not come back working properly, it came back the same. I am also 98% sure that this "unknown USB device" is my built-in webcam that has never once worked. So if someone wants to help me out and allow me to use my webcam that would be great!

A:Unknown USB Device (Device Descriptor Request Failed)

Hi there, can you first tell us what is the Name and Model number of your system?

What OS are you running

im sorry if you already listed this, as I cannot see your specs from the Windows Forum App..

I know that a similar question has been asked before but, not with the last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???My question is; has anyone heard of Windows 8.1 having driver WHQL problems?? Very.

Any/all ideas, appreciated.

ps, I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

A:Unknown USB Device (Device Descriptor Request Failed)

Is there only one USB port on the right hand side? Sometimes manufacturers connect internal devices via an unused USB port internally. USB ports are usually in groups of two, seeing only one port is usually a sign that the wiring has been redirected internally to something else like a Bluetooth adapter or wifi adapter. It may even be a card reader or touchpad. Is anything like that not working? If it is start looking for a driver for it.

I have had the Microsoft Wireless 2000 Keyboard and mouse for 10 months and it has been working fine. But recently when I plugged it in I got an error message which said :The last USB Device you connected to this computer malfunctioned. and Windows does
not recognize it.
I opened Devices and Printers and it said Unknown USB Device (Device Descriptor Request Failed).

Hello,I have been facing a problem with my USB devices for the past few weeks. Whenever I connect a USB device (mouse, iPhone or even a USB), I get the error Unknown USB Device (Device Descriptor Request Failed) Windows has stopped this device because it has reported problems. (Code 43). As a result, i am unable to connect any USB device to my computer which is very frustrating. In addition to that, I have also discovered that my Bluetooth Devices also shows a similar message Unknown USB Device (Device Descriptor Request Failed) Driver Error. I tried to connect devices (phone, a wireless headset) to my computer but that also failed. I have tried various solutions from the internet (disabling/uninstalling USB devices, reinstalling Bluetooth drivers, etc) but none of these seem to fix the problem. I do not know what the root cause of this problem and i would be very happy if you could guide me on this problem. Following are the details about my laptop and windows along with a screenshot of the errors: Laptop - Lenovo G50-70, Core i5, 8 GB RAMWindows 10 - Version 1809 (OS Build 17763.253) Would appreciate any help that you could provide.Regards,Usman

After installing Windows 10 anniversary update, I get the following error in the device manger: Unknown USB Device (Device Descriptor Request Failed)

Tried uninstalling and restarting PC. Reinstalled Windows made from media tool. Nothing fixed it. Did a google search and nothing has worked. No USB drivers on the PC maker's website.

Any ideas?

A:Unknown USB Device (Device Descriptor Request Failed)

You can try going into device manager > select show hidden devices and delete all "inactive" usb device appearances. In my example below, there would be four. Once done, reboot and try your device again:

Hey1.)So my mouse(Corsair Harpoon RGB) was recently just working fine until one night i unplugged it and put it into computer and on that computer it didnt work so i went back to my laptop to plug it in there, but it showed the same problem it didnt respond the logo didn't light up so i went to the device manager and it said *title. So how do i fix this is there something with my mouse is there something with my software?Oh yea and on top of that i have 2 more issues that i jut can't solve by myself.

2.) Unknown USB-device(port reset failed)3.)DVD Drive(optical drive) doesnt show up on the device manager but it sounds like it's working and it opens and closes.4.)Front ports of my PC doesnt work if i plug an USB in it doesnt do anything (it does work perfectly in the back)

I don't know though if i should make more threads but they somewhat relate to each other,that's why they are just in 1 thread. If you need to ask any question, need pictures , my specifications or anything else just ask me.Thanks in advance!Best regards Hao.

Hello, I seem to be having an issue with my Thinkpad T470p. I've had it for about a year and a few months ago, all the 3 USB ports stopped working and so did the integrated camera. It would work at times and then stop working. For the past 2 weeks, everything has completely failed. So far I've done the following: -I've reset the BIOS to default settings and still there is no change.-The USB ports are enabled in BIOS settings as well. -Fast startup is diabled-The autosuspend for USB devices has been disabled in the power settings as well-All drivers have been updated using the Lenovo System Updates-This is a fresh install of Windows 10 so there is no previous state that I can go back to. (It wasn't working when I was running Ubuntu either even with all the right drivers installed.)-Troubleshooting cannot seem to find a fix for the error either One weird thing though is that my WD Elemnts HDD works fine when plugged in to any of the USB ports but other than that nothing else works. Any and all help will be much appreciated. My warranty expired just before these issues started so I don't really think I can get it repaired by Lenovo services.

Im running windows 10 on an HP laptop, 64 bit, and i just got a micro usb to usb device so i can transfer stuff onto my phone. It worked when i first got it but now it comes up with a Device Descriptor Request Failed and a Code 43 error. Ive tried updating
the drivers, restarting my laptop, and plugging it into different usb ports but it still comes up with the error. Any suggestions?

I'm pretty sure everything is working as should, you're good minus the minor annoyance if all device connected through the USB Hub is recognized by Windows; if you right click Properties on the yellow triangle it probably says "The Device is working properly".

Can any help with this problem? Have a Pavilion G6 with no USB 3.0 as I am aware. USB (3 ports) not working.However, when the plugged the mobile, the mobile does get charged. Device Manager shows "Unknown USB Device (Device Descriptor Request Failed)". Running Windows 10 64 bit. Tried everything like uninstalling, updating etc as the information on the internet. Also, updated the drivers using Driver Easy but still getting the error. Any suggests, please? Thanks in advance. Sanil Sukumaran.

Hello, The left USB socket on my X250 has started to return the message Device Descriptor Request Failed, but the right hand USB works as normal. I rarely used the left hand one so I am unsure for how long this has been the case, but now I am very keen to start using a USB keyboard so I am very keen to get it working again.I have tried uninstalling the device and reinstalling, and searching for new drivers.Thanks in advance for any help,Dave

I'm experiencing slim keyboard not being recognized in the Windows 8.1The keyboard was working fine until just one day it just stopped working.I tried factory reset literally 8 times along with most recent BIOS update and dell's recommended update software. + power setting --> disabling power saving on USBIt still come up as unrecognized each time even with fresh reinstall.I was wondering if this is a hardware issue or just software bug from factory reset.I don't think there is a available driver for this kind of problem is there?

i have acer e1-571 notebook.running windows 10.from last few days my pc giving this error-Currently, this hardware device is not connected to the computer. (Code 45)

To fix this problem, reconnect this hardware device to the computer.

A request for the USB device descriptor failed.
i have tried all kind of suggestions
given by microsoft related this problem .but cant solved.card reader ,pen drive ,external keyboard ,or external mouse no one working.2.some random keys is not working .please fix my issue .

I had my Samsung Core Prime plugged in via usb, I'm guessing I pulled it out without ejecting, as now whenever i plug it in, gives Drive descriptor request failed. It's not the port or the cord as the phone's charging perfectly fine. I've restarted both devices multiple times, uninstalled the usb drivers, and a bunch more. Any suggestions?

After installing window on my laptop (Lenovo Ideapad 100) found out that the USB port are not working although if i plug in a phone it indictaed charging and i plug in my hard drive it shows the led light but the USB cant read any device not even a USB mouse works on the system . Please kindly help me with this error.

Most of the threads on this error are old, (2015) so I am starting a new one. I only notice it when I happen to be in the device manager. I have no problems with any of my connected USB devices (that I have observed).

I have tried uninstalling it, and rescanning and it pops up again, so apparently it is something that is connected. Without disconnecting All of my USB devices one at a time (which I am wont to do, as it is not bothering me, other than that it is there!) It has been there for quite a while, so apparently is not anything new being connected.

Is there no way to identify WHAT is connected to this port, or even what port it is?

BTW, it only shows up in the USB Controller section, no matching errors in any of the devices themselves!

I have two WD "My Book" 3.0 USB drives. Previously, they both worked fine. Now one of the two drives is getting a device descriptor request failed message. The other drive is fine. I have tried different 3.0 inputs on the system both in back and on top in the front. Any ideas on why the same drive isn't working? I have tried both on other systems and they work fine. The other systems I have tried them on are WIN7 and WIN 8.1.

Solved! View Solution.

A:usb 3.0 drives getting device descriptor failed error

Hi there slovey Have you, by any chance tried with another USB cable? I wouldn't make sense to change things as the device works on other systems but it wouldn't hurt to use the other My Book's cable with the problematic one just to rule this out as a potential cause. I would also check this thread and see if the offered solutions there help. Keeping your OS, BIOS and drivers up to date is also an important part of the troubleshooting process. I'd also check if there's a new update specifically for the driver responsible for the communication between the drive and the system. Post back if you need more info! Captain_WD.

hello i'm an embedded developer. i have an usb type ic programmer to burn microcontroller. now i'm getting this error "Unknown USB Device(Device Descripter Request Failed)" while plug my usb programmer into my pc socket. but this same hardware support in my friend same hp430 pc.

I have a problem that bugs me for years, I never intentionally solved it, sometimes those errors disappears and all USB ports work fine, sometimes they do not. So anyone can help me please, it would be great.

Some of my ports do not work all the time, I cannot identify a specific moment. Inside the Device Manager, Universal Serial Bus controllers, I get 1, 2 or more "Unknown USB Device ( Device Descriptior Request Failed )", sometimes more sometimes less.

CPU: Intel Core i7 3770Motherboard: AsROCK H77 Pro4/MVPWindows 10 all available updates downloaded and installed as of today, and everyday. The problem appeared on Win 8 or 7, not sure when. So it's not necessarily Windows 10 specific. I ported it to 10. Here is what they look like:http://prntscr.com/d6rm6k

Bios is up to date. Chipset drivers updated, various solution tried from googling, I even managed to make all USB ports stop working testing some of these solutions, I had to restore windows from a ghost image I had.

It's like these USB ports remain suspended sometimes.

Any advice on what to try? The most annoying part is that from the frontal USB ports some stop working randomly too.

I do not over clock. I have the ram overclocked in the BIOS using XMP to 3000 speed, but that's it.

Here is my situation, and I am baffled and feel super deflated over this mess as I run a small project studio for video and audio work and this is causing me to fall behind on projects.

I am getting constant on screen pop up notifications that a recent USB device isn't recognizable or 'has malfunctioned and windows doesn't recognize it' along with constant USB connect/disconnect sounds. I just built this custom PC this past week and everything seemed fine for a couple days, and then this started.

When it does this, I go into device manager, and I get a yellow exclamation mark under the USB list that says 'Unknown USB Device (Device Descriptor Request Failed). I have hit google search and tried every single suggestion I could find including the following:

-Blowing all the dust out of all the ports, although i doubt that was an issue because the case and motherboard are brand new.

-Going into device manager, and disabling or uninstalling the device that is giving the error. It pops right back ... Read more

I have tried a few different windows images, windows troubleshooting feature, and the latest versions of the drivers.I've tried uninstalling and reinstalling drivers, disabling and re-enabling, re-imaging, updating windows. None have had the effect of actually making it work. I'm running win 10.0.10240, on dell latitude 5285 and 5289. This is affecting the entire Intel Integrated Sensor Solution Driver and all the included sensors, compass, accelerometer, gyroscope GPS and ambient light.

hardware id: HID\Vid_8087&Pid_0AC2I would like to resolve this so that we can order tablets and have them work right in our org.

I've used MMA to develop a USB device before and was able to look at the raw data in the message view to ensure the correct data was being sent in the descriptors. This does not appear to be showing up any longer. I'm currently using MMA 1.4
When I click the message that shows a USB transaction and scroll to the bottom of the Details window, the DeviceDescriptor is in the list, but it does not show any data and the Message Data window shows: "No Data Source data not available for display"
The UsbLength field clearly indicates that 18 bytes have been transferred and the device is working properly so I know the data was sent. How do I inspect the raw data for the device descriptor?

Hi, I just bought a new HDD today and freshly installed windows 10 and have ran into this problem: when I plug in my wireless XEOX Pro Analog Gamepad from Speedlink I get the "Unknown USB Device (Invalid Configuration Descriptor)" error. I'm adding the screenshots.

This device worked perfectly on windows 7 yesterday, so the controller definitely isn't damaged physically and it does work on a different PC(windows 7).

Hi,
I have an USB device (an embedded system that I am developing) and associated driver.
It has one interface with two endpoints (BULK IN and BULK OUT) and control endpoint.
When I connect that USB device to PC, then device driver is getting associated with device and I am able to use the device.

Now I have updated USB device descriptor to have one more interface (all other information like VID, PID are same and also existing interface is not altered). Now it has: one control endpoint, one interface with BULK IN and BULK OUT and another interface
with BULK IN endpoint.

When I connect this USB device with modified device descriptor, USB driver is not getting associated and giving me error code: 10 (0xA).

Device driver software is from 3rd party.

Now I am not sure if error is thrown by windows kernel or device software.
Please help me in debugging this.

Any log files/events that can be enabled when device is connected and how driver is loaded, what checks are performed by kernel to load the driver etc (I believe it only looks at VID and PID).

FYI: Same setup works on Linux environment (looks liek linux just ignores this additional interface added)

When the device is not recognized, unplugging and replugging the USB cable makes no difference to the situation. In order to correct the issue, I disable and then enable via Device Manager (which also involves a restart).

This pattern is extremely repeatable.

I am working with WinXP SP2, Pentium, 2.8 GHz, 504 MB RAM.

This PC was returned from a customer site - the PC and USB device are used in a machine my company manufactures. Apparently this issue just started happening one day. We want not only to correct the issue, but in fact to understand the root cause and ensure it will not happen again in the future.

Any suggestions would be greatly appreciated - thanks!

A:USB Device Recognized / Not Recognized based on shut-down method

You could try reinstalling the usb drivers.JohnWill has fix that is worth a try

Johnwill's solution

Create a file with NOTEPAD containing the following lines and save it as FIX.REG-------------------------- Use text after this line --------------------------------REGEDIT4

"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.Open Device Manager.View, Show Hidden Devices.Uninstall all devices under USB Controllers.Uninstall all devices under Disk Drives that you know are not present.Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions. __________________Microsoft MVP - Shell/User
